The negative relationship between androgens and the Bezold-Jarisch reflex (BJR) has been demonstrated, but no studies evaluated physiological influence of testosterone on this reflex. We male rat castration BJR, cardiac morphometric parameters, plasmatic angiotensin converting enzyme (ACE) activity. After (CAS), rats were divided into 24 72 h (CAS24H, CAS72H), 7 21 days (CAS7D, CAS21D) groups. BJR was studied by administering increasing doses phenylbiguanide (PBG; 1.5-24 μg/kg) at different...
